  由於明顯的成本優勢,網際網路語音傳輸協定(VoIP)已經吸引眾多的注意。目前有三種主要的網際網路語音通訊協定,包括Internet Engineering Task Force(IETF)提出的Session Initiation Protocol(SIP),International Telecommunication Union(ITU)提出的H.323,以及IETF與ITU共同提出的Media Gateway Control Protocol(MGCP)與MEGACO。Integrated Call Agent(ICA)整合了這些網際網路語音通訊協定。
  在本論文中,我們將網際網路語音目錄服務(ITDS)的功能加入至ICA中,以在各個ICA之間交流使用者的註冊資訊。我們採用階層式Mobile IP的概念來設計ITDS,所以加入ITDS功能的ICA除了可以在建立通話連線與繞送信令時追蹤被呼叫端,亦可支援使用者的小範圍移動。我們也延伸ICA的架構成為service platform,以提供新服務給使用者。透過service platform,使用者可以管理(啟動或停止)他所註冊的服務,ICA則可在適當的時機為使用者起始特定的服務。
  VoIP has attracted much attention due to its distinct economic advantage. There are three main VoIP signaling protocols, including Session Initiation Protocol (SIP) proposed by Internet Engineering Task Force (IETF), H.323 proposed by International Telecommunication Union (ITU), and Media Gateway Control Protocol (MGCP) and MEGACO proposed by IETF and ITU. Integrated Call Agent (ICA) is an architecture that integrates the protocols in one entity.
  In this thesis, we enhance the ICA with Internet Telephony Directory Service (ITDS) to interchange the users’ registration information between ICAs. We adopt the concept of hierarchical Mobile IP to design the ITDS, so that the ICA architecture with ITDS can not only locate the callee when setting up a call and routing the call signaling message but also support the user micro mobility. We also extend the ICA architecture to a service platform to provide supplementary services for a user. In a service platform, a user can manage (activate or deactivate) the supplementary services he has subscribed, and an ICA can invokes a specific service for a user when necessary.
